Extraosseous vulvar chondroma: a case report

Area of Science:

• Oncology
• Pathology
• Pediatric Surgery

Background:

• Extraosseous chondromas are benign cartilaginous tumors, typically presenting on the extremities.
• While rare, they can occur in various locations, including the pelvis, oral cavity, and viscera.
• Surgical excision with a safety margin is the standard treatment, with low recurrence and no reported metastasis.

Observation:

• An 11-year-old girl presented with a painless, solid tumor on the mons pubis.
• Surgical removal revealed a yellowish, shiny, cartilage-forming tumor.
• Microscopic examination confirmed the diagnosis of extraosseous chondroma.

Findings:

• This case represents the first reported instance of an extraosseous chondroma in the vulvar region.
• The occurrence of extraosseous chondromas in pediatric patients is infrequent.
• The tumor was successfully excised with no recurrence observed after two years.

Implications:

• This case expands the known anatomical distribution of extraosseous chondromas.
• Highlights the importance of considering rare diagnoses in pediatric vulvar masses.
• Contributes to the understanding of benign cartilaginous tumors in children.
